indicating the weight is "Locked On". The
animal’s weight must be greater than 2.5% of
the scales "capacity" weight before the system
can "Lock On."

In order to break the lock, 50% of the
displayed weight must be either added or
removed from the scale. The "Locked On"
weight can be "rechecked" by pressing the
[ZERO] key on the front panel. This breaks
the "lock" and the scale recalculates the
weight.
